Classical conditioning

Classical conditioning is a learning procedure in which a person is conditioned to have an involuntary response to something that is not natural. It was first studied in detail by Ivan Pavlov with his dogs; he rang a bell when he was preparing to give dogs their food, so the dogs learned to associate the bell with food. Eventually, whenever the bell rung, the dog would start to salivate in anticipation of food. Together with operant conditioning, classical conditioning became the foundation of behaviorism.
